Patent GB-765454-A (GB)
Title: Improvements in or relating to winch drives, especially for cable-tool drills
IPC: B66D1/14
Filed: 1952-03-27
Abstract: 765,454. Control for winch for oil drill. RUSTON-BUCYRUS, Ltd. March 27, 1952 [April 5, 1951], No. 7870/52. Classes 78 (2) and 78 (5). [Also in Group XXI] A drive for oil drill winch drum 31 includes a prime mover 41-38 which, simultaneously, engages the drive of said drum 31 and releases the brake 52 thereof. The line to the drill 26 passes, from winch drum 31, around sheave 24, spudding sheave 25 and crown sheave 20, the latter being mounted upon yieldable member 22 so that, when extra line is required, the crown sheave is pressed downwards to actuate a switch which causes the line to pay out. Thus, in Fig. 3, the switch permits compressed air to enter cylinder 38 to cause piston 41 to move to the left. Thus piston 41, sliding in keyways, engages nut 47 by means of teeth 46 and so exerts on screw 48, and therefore on shaft 36, both a thrust and a torque. The thrust to the left disengages brake 52 and so permits the shaft 36 to rotate under the torque until nut 47 moves to actuate switch 70 and allow the piston to return to its original position. This rotation of shaft 36 is transmitted through gearing 35-34-33 to pay out the line from the drum so as to relieve the tension in said line. In normal operation, the drum 31 is driven from a driving motor through a clutch (not shown) which may be coupled with brake handle 60 so that brake 52 is released when the drill is to be elevated; or alternatively, handle 60 may be omitted and the drive from gear 33 to drum may be through epicyclic gearing, the ring gear of which may be connected to the driving motor. In a second embodiment, sheave 20 becomes the spudding sheave and sheave 25 is resiliently mounted to operate a switch as above described. This releases air to operate piston 124 (Fig. 6) in cylinder 123 so that detent 143 engages ratchet wheel 108 to rotate the winch drum whilst movement of said cylinder causes, through lever system 121-120-116, the release of brake 114. In a modification of the second embodiment the switch operates an electric motor which drives a screw and nut to similarly operate rotate detent 143 and release brake 114.
